What you may notice:
More frequent awakenings during the night and a longer time needed to fall back asleep.
Helpful habits:
Morning sunlight exposure can help reset your circadian rhythm. In the evening, limiting blue-light exposure from phones and televisions at least an hour before bed can support better rest.
2. Changes in Temperature Regulation
With age, the body’s internal “thermostat” becomes less efficient. The ability to sweat to cool down or constrict blood vessels to retain warmth slows, making both heat and cold feel more intense.
What you may notice:
Feeling chilled indoors or overheating more quickly in warm weather.
Helpful habits:
Dress in breathable layers and stay well hydrated. Adequate water intake plays an important role in regulating body temperature.
3. Slower Digestion and Nutrient Absorption
Digestive efficiency naturally declines as stomach acid production decreases and intestinal movement slows. This can affect how well the body absorbs essential nutrients such as vitamin B12, iron, and calcium.
